“Exploring the Join Distribution of Fitness Effects for Beneficial Mutations in Yeast.”

Friday, March 30, 2018
12:00 PM
RRI 101

Abstract: We previously developed a lineage tracking system to follow the dynamics of adaptive evolution of 500,000 isogenic haploid lineages of Saccharomyces cerevisiae under a glucose limited regime. By tracking the lineage tags over time, we showed that ~20,000 of the lineages gained a beneficial mutation during the experiment, which occurs over only 240 generations. Furthermore, we have also been able to generate a distribution of fitness effects for these lineages (Levy, Blundell et al, Nature (2015)). We isolated thousands of clones belonging to specific lineages, remeasured their fitness, and whole genome sequenced ~120 haploid clones from independent lineages that had gained beneficial mutations. We found that the RAS/cAMP/PKA pathway and the Tor pathway are frequently targets for adaptation under our conditions, uncovering almost 80 mutations in these pathways. In several cases where a gene has a paralog, beneficial mutations are recovered in one paralog significantly more frequently than that other. We have also found that even when mutations affect the same pathway, that the fitness conferred by mutations in a given gene tends to be specific for that gene, and distinct from the fitness effect of mutations in other genes in the pathway (Venkataram et al, Cell (2016)).

We next measured the fitness of these lineages under alternative conditions to determine in what phase of the growth cycle the beneficial mutations provide their fitness benefit, and whether there are within growth cycle fitness tradeoffs. By extending or shortening the length of exponential phase or stationary phase, we found that lineages carrying mutations from the same pathway show similar patterns of fitness change. Furthermore, Ras pathway mutants accrue fitness from spending time in the respiratory growth phase, but this fitness benefit is only manifested in the next growth cycle, as a shortening of lag phase. We also find that these mutants show deleterious effects in stationary phase, suggesting intrinsic tradeoffs between different parts of the growth cycle (Li et al., Current Biology (2018)).

Finally, to generalize beyond closely related experimental conditions, we have evolved both haploid and diploid yeast in several environments, using a double barcode approach, wherein the evolution condition is encoded in the second barcode. We have isolated adaptive clones from each of the conditions, then pooled them, and remeasured their fitness across each of the conditions, to understand how the ways in which beneficial mutants may either be generalists or specialists, and the ways in which they might tradeoff.

“Skeletons, mutants and ontologies: what can we learn from linking phenotypes and genetics on a large scale?”

Thursday March 29, 2018
2:00 PM
RRI 101

Abstract: In contrast to the plethora of computational tools for comparative genomics, there are relatively few for the comparison of phenotype polymorphism and divergence. Yet, the systematics literature is replete with descriptions of phenotype differences among fossil and living organisms. For the past decade, the Phenoscape project has been exploring ways to compute over this kind of descriptive phenotype information by leveraging the ontologies developed within the model organism community. Here, I describe lessons from applying these semantic technologies to test cases in vertebrate skeletal evolution, with a focus on the application of identifying highly diverged, but statistically similar phenotypes. One key question is how well candidate genes obtained using this approach for major events in phenotype evolution, such as the fin-to-limb transition in tetrapods, agree with, conflict with, or complement, candidate genes from literature. Can semantic reasoning over phenotypes augment the expert knowledge of biological specialists?

Graduate Research Opportunities at DOE National Laboratories

The Department of Energy’s (DOE) Office of Science is pleased to announce that the Office of Science Graduate Student Research (SCGSR) program is now accepting applications for the 2018 Solicitation 1.  Applications are due 5:00pm Eastern Time on Tuesday, May 15, 2018.

Detailed information about the program, including eligibility requirements and access to the online application system, can be found at: https://science.energy.gov/wdts/scgsr/

The SCGSR program supports supplemental awards to outstanding U.S. graduate students to conduct part of their graduate thesis research at a DOE national laboratory/facility in collaboration with a DOE laboratory scientist for a period of 3 to 12 consecutive months—with the goal of preparing graduate students for scientific and technical careers critically important to the DOE Office of Science mission.

The SCGSR program is open to current Ph.D. students in qualified graduate programs at accredited U.S. academic institutions, who are conducting their graduate thesis research in targeted areas of importance to the DOE Office of Science. The research opportunity is expected to advance the graduate students’ overall doctoral thesis/dissertation while providing access to the expertise, resources, and capabilities available at the host DOE laboratories/facilities. The supplemental award provides for additional, incremental costs for living and travel expenses directly associated with conducting the SCGSR research project at the DOE host laboratory/facility during the award period.

The Office of Science expects to make approximately 50 awards in 2018 Solicitation 1 cycle, for project periods beginning anytime between October 29, 2018 and March 4, 2019.

Since its inception in 2014, the SCGSR program has provided support to over 300 graduate awardees from more than 100 different universities to conduct thesis research at 17 DOE national laboratories across the nation.

The SCGSR program is sponsored and managed by the DOE Office of Science’s Office of Workforce Development for Teachers and Scientists (WDTS), in collaboration with the six Office of Science research programs offices and the DOE national laboratories/facilities, and program administration support is provided by the Oak Ridge Institute of Science and Education (ORISE).

Making postdocs “less invisible” in academia

Friday, March 23, 2018
12:00 PM
RRI 101

Abstract: Future of Research (FoR) aims to champion, engage and empower early career scientists with evidence-based resources to improve the scientific research endeavor. As part of this goal, we study academic policies that affect postdocs. Postdocs make up a large portion of the biomedical workforce. However, they are typically considered the “invisible” population in academia. Lack of data on postdoc numbers, titles and pay contributes to the difficulty of devising novel, or improving existing, policies for postdocs. Our studies examined national postdoc trends in these areas. We monitored institutional postdoc salary policies as a result of labor law changes; obtained actual postdoc salaries in U.S. public institutions; and found large institutional variability in reporting postdoc numbers in an established NSF survey. Given these findings, we call for better measures to assess postdoc population trends. We hope these efforts will make postdocs a “less invisible” population, and contribute to an overall recognition of the need for increased academic transparency.

Decoding the noncoding messages in messenger RNAs

Tuesday, March 6
3:30 PM
RRI 101

Abstract: RNA plays central roles in transmitting and regulating genetic information. While the genetic code is simple and universal, the code controlling the spatiotemporal regulation of mRNAs remains poorly understood. My research aims to understand the fundamental mechanisms of gene regulation at the RNA level by using integrated computational and experimental approaches. I will highlight my recent work that has uncovered widespread roles of RNA secondary structures in regulating human mRNA biogenesis and metabolism. In addition, I will discuss my ongoing work on the translation of noncoding sequences in mRNAs and the systematic discovery of mRNAs with protein-independent functions.

Mixotrophic mediators of planktonic communities: Connecting models with data to predict dynamics and function

Tuesday, March 6
12 PM
AHF 153 (Torrey Webb Room)
 
Abstract: Mixotrophic organisms, which “mix” photosynthesis and heterotrophy to meet their metabolic needs, are widespread in planktonic communities. This physiological trait allows them to function both as primary producers and as grazers, supplementing their carbon needs with photosynthesis when prey are scarce and scavenging materials from other species when nutrient supplies are low. As such, they play an important dual role mediating community production and nutrient cycling. In recent years, mixotrophs have received increasing attention for this reason, with both empirical and theoretical approaches employed to incorporate them into our understanding of marine planktonic communities. In this talk, I describe recent work focused on how mixotroph traits (particularly those governing photophysiology and grazing) determine community dynamics and function. I formulate mechanistic models for the interactions between mixotrophs, their resources, and their competitors, validate these mathematical models with empirical data, and then use the models to interpret field observations of mixotroph abundance. These models identify environmental conditions under which mixotrophs may be the key mediators of ecosystem function, highlighting new avenues for experimentation and incorporation into ocean-scale approaches.
